Title: Improvements in transformer of threephase currents to constant direct current
IPC: H02M1/30
Filed: 1918-01-08
Abstract: 147,028. Corbino, O. M. May 26, 1917, [Convention date]. Addition to 112,938. Void [Published under Sect. 91 of the Act]. Commutator switching-arrangements; converting alternating and direct currents.-Three-phase currents are. rectified by a rotary mercury-jet switch comprising a double jet g<1>, g<2>, Fig. 1, and three contact plates d<1>, e<1>, f<1> spaced 120 degrees apart. The contact plates are connected to the phase leads 1, 2, 3, and the direct-current load k is connected to the mercury mass and to the neutral point l. The resultant intermittent current is made practically constant by inserting an inductance 0 in series with the direct current load, and connecting an electrolytic cell V across the inductance and load as shown in Fig. 2. A few turns O<1> of the wire carrying the intermittent current are wound on the core of the inductance O. The mutual inductance of the windings 0, O<1> assists in maintaining the current through the load constant during the intervals between successive impulses. The three-phase supply may be connected to the jet apparatus through a transformer or auto-transformer and tappings may be taken to connect to the motor driving the jet apparatus. A star-connected transformer winding may be used to give an artificial neutral point.

Title: Improvements in jigging conveyors
IPC: B65G27/14
Filed: 1939-06-29
Abstract: 530,720. Jigging-conveyers. SMELY, V. June 29, 1939, No. 19003. [Class 78 (i)] In the operation of jigging conveyers by liquid under pressure circulating in a closed system, the pressure is maintained by gaseous fluid above the liquid in the supply reservoir. The hydraulic cylinder a, carrying a piston connected to the conveyer (not shown), is connected to a storage chamber b and exhaust chamber c. The liquid in the chamber b is placed under compression by adding compressed air and the pressure is maintained by the circulating pump d, driven from the motor e, which draws exhaust liquid from c and forces it into the storage chamber. A slide valve f, controlling the passage of the fluid automatically, is controlled by pumps h<SP>1</SP>, h<SP>2</SP> on a pivoted lever h rocked by the cam g on an arm projecting from the moving piston. The valve is set so that the conveyer is given a gradual forward acceleration and sudden quick return stroke ; which may be assisted by an air cushion, spring, or by gravity. In some cases the sudden quick stroke may be the power or forward stroke and the accelerated stroke, the return. In a modification a pilot valve operated from the moving piston is used to operate the main valve f. Also in this construction the piston is stepped so that an annular chamber is formed in its forward part. This chamber is connected to the pressure supply and serves to assist in propelling the piston backward on the return stroke.

Filed: 1928-07-06
Abstract: 294,207. Kodak, Ltd., (Assignees of Frederick, C. W.). July 20, 1927, [Convention date]. Optical systems.-In optical systems applicable to colour photographic processes of the kind utilizing a filter of colour bands at the objective and a sensitive emulsion having minute lens elements upon its front surface as described in Specification 10611/09, [Class 98 (ii), Photographic processes &c.], it is necessary that the filter when viewed from any individual lens element should subtend the same angle in both the taking and projecting systems. To avoid compensating means when objectives of different focal length are used the colour screen is positioned in front of the taking objective at the point which is conjugate to a point distant from the rear focal plane of the objective by an amount equal to the distance between the rear focal plane of the projection objective and the virtual image of the colour screen associated therewith. In practise, the colour screen C I D, Fig. 3, is mounted as closely as possible in front of the projection objective and the position of the virtual image C' I<1> D' with respect to the focal plane O<1> determined. A taking objective, Fig. 4, is selected having a front .surface just within the position i determined for the colour screen, that is an objective having the front Gauss point well back within the objective. In the example described this point is behind the posterior Gauss point. To enable the screen to be accurately adjusted it is carried on a cap fitting over the front of the camera objective. The ratio of the effective diameters of the respective colour screens is equal to the ratio of the focal lengths of the objectives. Numerical details of the proportions of two suitable lenses are given in the Specification.

Title: Improvements in apparatus for comparing frequencies of electric oscillations
IPC: G01R23/00
Filed: 1945-08-01
Abstract: 596,741. Frequency and phase measurements. BRITISH BROADCASTING CORPORATION, GOURIET, G. G., and HAMMANS. R. H. Aug. 1, 1945, No. 19830. [Class 37] For comparing two frequencies f1, f2, e.g. nearly equal frequencies, one is applied at C.D., Fig. 1, to develop a stepped saw-tooth oscillation b, Fig. 2, of frequency f1, or a sub-multiple thereof, which is applied to the X-plates of a cathode-ray tube 13, Fig. 1, and the other is applied at AB to develop pulses of frequency f2 which are applied to the Y-plates of'the cathode-ray tube. The cathode-ray thus traces a line d, Fig. 2, having bright spots s due to the steps of the saw-tooth wave with a peak p due to the pulse. If f 1=f2, the peak p remains stationary ; if f1 and f2 are unequal, the peak moves, and its velocity is a measure of the difference of f1 and f2. The invention is applicable where f1 is nearly equal to nf2 (n being integral) or where f1 is nearly f2/n (n being 1 ... 5). The pulses are also preferably applied to the control grid 1 of the cathode-ray tube to increase the brilliance of the peak p. Since a pulse of the form h, Fig. 2, giving a uniform brightness g of the peak p is not readily obtainable, a limiting diode 19, Fig. 1, changes the pulses j, Fig. 2, to l which would produce a peak m, but an inductance 16 produces a delay in the pulse so as to develop a uniform peak p. Phase shift of the control frequency will produce peaks of the form shown in e, f, Fig. 2, so that progressive displacement of the mean phase is revealed by displacement of the peaks as a whole. Specification 566,215, [Group XL], is referred to.
